SEAL PRESS.

Applicationl led August 31, 1925. Serial No. 53,453.

The purpose of this invention is to provide an improved and simplified construction of a seal press adapted to be constructed of met-al stampingsand affording convenience for withdrawing the seal member for rectifying or replacing the seal elements. It consists in the elements and features of construction shown and described as indicated in the claims.

In the drawings:

Figure 1 is a perspective view of a completely assembled seal press embodying this invention.

Figure 2 is a perspective view of the three principal stamped metal parts of the seal press, dissected.

Figure 3 is a medial longitudinal vertical section of the press showing the die members in elevation.

Figure 4 is a side elevation of the removable die carrier, removed from` the press.

The seal press shown in the drawings comprises three principal elements, each of which is a metal stamping, viz., a base member, A, standard, B, and operating lever, C. The base member is substantially flat with ay central longitudinal part struck up, as seen at A1, leaving a marginal portion, A2, for resting upon a flat support, said `upstruck central longitudinal portion, A1, af fording seat for the standard, B, which is formed from a sheet metal blank folded at parallel lilies to produce a channel member open from end to end, and with the sides,

r B1, B1, parallel, and the connecting web, B2,

dim-ensoned for seating upon the up-struck central longitudinal area, A1, of the base member to which said standard issecured rigidly by' any convenient means, preferably spot welding. The standard member is given the form of a pair of rigid jaws by deep notches, B3, cut in from the forward end in both of the upright sides, said notches being registered or aligned with each other horizontally. |The operating lever member, C, is struck from a metal blank forming a downwardly-open, upwardly-curved channel for the handle or longer arm, C1, from which extend parallel lugs, C2, G2, constituting the shorter arm of the lever, and between which at their extremities there .is mounted a cam roll, 10. This operating lever is mounted between the parallel sides of the channel standard, pivoted thereto at .the upper forward corner by a pivot bolt, D.

The press comprises, beside the three metal stamping parts mentioned and described, the seal carrier which consists of two flat bars, 12 and 13, pivoted together at one end, and at the opposite ends enlarged as seen at 12a, 13afor carrying the co-operating die enclosing cups, 2O and 21, which are spot-welded or otherwise equivalently permanently secured to said enlargements respectively ywith their cavities facing each other. bars, 12 and 13, at their pivoted end is a spring, 15, which reacts upon the two bars for holding them normally spread apart at the seal-'carrying ends. The bars, 12 and 13, throughout their length back of the enlargement, 121, 131, are of width to enter and fit quite closely between the parallel upright sides of the channel standard bracket, B; and the facing edges of the rigid jaws formed by the notches, B3, are recessed or notched at their upper and lower edges respectively, as seen at 17, 17, and 18, 18, to engage and thereby definitely position lthe enlargements, 121, 13a, when the seal carrier has been thrust in from the forward end of the standard entering the seal carrier enlargements with the cups thereon between the upper and lower jaws; and when thus entered the reaction of the spring, 15, holds the enlargements, 121, 13a, safely in the notches, 17, and 18, respectively.

In detail the construction of the bars, 12 and 13, for pivoting together at their rear ends is that the blanks from which they are formed have transversely projecting lugs, 12, 12b, and 13b, 13b, which are folded at right angles to their original plane, the lugs of one jaw,the upper jaw, 12,-being folded so as to be spaced narrowly enough to enter between the more widely folded lugs, 131, of the lower jaw, as seen in Figure 3, and the spring, 15, is coiled on the pivot between the more narrowly folded lugs ofthe upper jaw. For stopping the operating lever at a proper upward limit of swing of the handle arm, a pin, 25, is set through the vertical sides of the channel standard extending.

across the channel at a position to be encountered by the short arm of the lever at the position to which it will be forced by the Coiled around the pivot of the two reaction of the spring, 15, spreading arnis of the die Carrier to seat the upper die-carrying enlargement, 12?, against thev lower edge of the upper jam-that is, at open or separated position of the die members.

II elaiin :-z

l. A seal press and the like Comprising a hollow rigid jawed open front and open top standard: a bell crank lever comprising a longer and a shorter arm t'ulcruined in the upper part of thestandard with the longer arm extending out through the open top and theshorter arin depending in the cavity ot' the standard norin'ally trending back troni the fulcruin; a seal'ealrrier comprising two equal bars'hinged together at one end and enlarged at the opposite' end for carrying respectively the (3o-operating seal nieinbers, and a spring reacting about their' pivot tor holding the seal carrier enlaigeiiieiit nornia'lly spread apart; said seal carrier being dimensioned as to width ot the bars back ot the enlargements for entering the open front of the standard and ittingin the l'iori'zontal vwidth ot the cavity, said enlargement'being diinensioned tor entering between the rigid jaws, said jaws having notched recesses 'for seating the enlargements respectively.

2. A seal press and the; likeV comprising a standard Consisting of a` base and parallel Lip-standing brackets made rigid with the base and deeply notched at their lforward ends to torni Jforwardly-open rigid jaws; an operating lever ulcruined between the brackets at their upper part having an arni depending from the tulcruin; a seal carrier comprising a pair of arins'hinged together at one end and at the other end enlarged and adapted for mounting eo-operating seal ineinbers, saidI arins back of said enlargeinent being adapted to be entered and to tit between the standards; said standards having means for engaging the. seal enlargements to position theV seal carriers in the standards.

ln a seal press and the like, a standard .tor seal inenibers and operating means, coniprising a base, and an upright mounted on the base and adapted 'for mounting on it a xed seal n'ieinber and the like, said upright consisting ot a' unitary ineinber ot upwardly open channel terni, the channel extending the ventire length ot' said ineinher and troni its upper open edge to a depth below the mounted position of the fixed sealfmember haring its sides upright and parallel and the bottoni web seated on and secured rigidly to the base.

el. In the. construction' 'defined in claim 3, the channel sides being notched at their forward edges for adn'iitting seal nienibers and the like, and being extended longitudinally and upwardly troni the back of the notch to afford rigidity compensating for the weake-ning by the notches, and an operating handle pivoted between the channel sides at the upper forward corner of the notched end, adapted to l'old down between the channel sides throughout the entire horizontal length of thel latter.

In testimony whereof, l have hereunto set iny handat Chicago, lllinois, this 25th day of August, 1925. f
